You may notice several changes after your parent has returned from a deployment with a
mild traumatic brain injury (mTBI). These changes happen in four main areas: cognitive
abilities (or your parent's ability to remember certain things and concentrate), emotional
responses (moodiness or not knowing if your parent will be happy, mad, or sad), physical
representation (having headaches or feeling tired often) and communication abilities (your
parent may not want to talk to others as much).
